解决方案
The following instructions provide a workflow to create a basin model using the Hydrology toolset from the Spatial Analyst toolbox.


  1. Run the Fill tool to correct the data resolution or to round elevations to the nearest integer value. a. In ArcCatalog, navigate to Toolboxes > System Toolboxes > Spatial Analyst Tools > Hydrology > Fill. b. Use a digital elevation model (DEM) as the 'Input surface raster'. c. Verify the path name for the 'Output surface raster'. d. If necessary, input the Z-limit. e. Click OK.
  2. Run the Flow Direction tool. a. In ArcCatalog, navigate to Toolboxes > System Toolboxes > Spatial Analyst Tools > Hydrology > Flow Direction. b. Use the output from Step 1 as the 'Input surface raster'. c. Verify the path name for the 'Output flow direction raster'. d. Click OK.
  3. Run the Basin tool. a. In ArcCatalog, navigate to Toolboxes > System Toolboxes > Spatial Analyst Tools > Hydrology > Basin. b. Use the output from Step 2 as the Input flow direction raster. c. Verify the path name for the Output raster.
